Jonas Brothers tour: Fans stunned as Nick Jonas runs off stage during Prague concert

Jonas Brothers star Nick ran off-stage during a show in Prague on Tuesday night (October 16) leaving the crowd baffled. Awkward giggles can be heard in a video captured by one of their fans, before people begin to realise his exit may not be part of the act.

It has been alleged someone in the audience had been shining a laser at the singer. A video posted to TikTok shows the drama the drama unfold, captured the 32-year-old appear to be startled after noticing the beam shining in his direction - before he stood and fled the stage, making a 'time out' sign.

Bandmates Joe Jonas, 35, and 36-year-old Kevin left soon after, followed by the entire band, onlookers said, but returned after a short stoppage. After the incident, fans took to social media to post footage, as well as give accounts of a minutes-long stoppage after spotting the laser.

In the clip, Sucker star Nick is seen sitting on a chair before suddenly standing up, appearing to turn to his security team before making for the stage exit. As he left, he repeatedly made the 'time out' sign with his hands before speeding out of sight.

The band has made no official comment on the incident, but fans have been quick to voice their concerns online in a stream of supportive posts.

The Jonas Brothers, formed in 2005, shot to fame after starring in their own reality show - Jonas Brothers: Living The Dream - and are set to mark two decades in showbusiness next year. They also starred in the Disney movie, Camp Rock, with Joe featuring as the romantic lead, opposite Demi Lovato.

Raised in Wyckoff, New Jersey, Kevin, Joe and Nick were nominated for the Best New Artist Grammy in 2008, and picked up an American Music Award for Breakthrough Artist.

They have gone on to sell more than 17 million albums worldwide, with their latest long-player - The Album - hitting shelves in May last year.
